Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications):

CY74FCT162244TPVC from Cypress Semiconductor Corp and 74FCT162244ATPVG8 from Renesas Electronics Corporation are direct parametric equivalents with active product status. Both maintain the 4.5V ~ 5.5V supply voltage range, 24mA output current, and -40°C ~ 85°C operating temperature. CY74FCT162244TPVC is available in bulk packaging, while 74FCT162244ATPVG8 is supplied in tape and reel format. Both are ROHS3 compliant.

For Higher Output Current Applications:

74FCT16244ATPVG from IDT and 74FCT16244CTPAG8 from Renesas provide increased output current capacity (32mA high, 64mA low) while maintaining the same supply voltage and operating temperature range. These parts are suitable for applications requiring higher drive capability. 74FCT16244ATPVG is active, while 74FCT16244CTPAG8 is obsolete.

For Lower Supply Voltage Systems:

74FCT163244APVG, 74FCT163244APVG8, 74FCT163244CPVG, and 74FCT163244CPVG8 operate at 2.7V ~ 3.6V supply voltage with reduced output current (8mA high, 24mA low). These are suitable for low-voltage applications and are all active products from Renesas Electronics Corporation and IDT.

For Low-Voltage with Extended Temperature Range:

SN74LVC162244ADLR from Texas Instruments operates at 1.65V ~ 3.6V with extended operating temperature range (-40°C ~ 125°C). Output current is reduced to 12mA for both high and low states. This part is active and suitable for low-power, wide-temperature applications.

For Legacy System Maintenance:

74ACT16244DL from Texas Instruments is classified as Last Time Buy and maintains identical electrical specifications to the original part (4.5V ~ 5.5V, 24mA output current, -40°C ~ 85°C). This part is suitable for maintaining existing designs but has limited availability.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC162244ADLR as a direct replacement for 74FCT162244ATPVCG4?

A: SN74LVC162244ADLR is functionally equivalent but operates at a different supply voltage range (1.65V ~ 3.6V versus 4.5V ~ 5.5V) and has lower output current (12mA versus 24mA). It is suitable only if your system design can accommodate these electrical differences. The extended operating temperature range (-40°C ~ 125°C) provides additional margin.

Q: What is the difference between 74FCT162244ATPVG8 and CY74FCT162244TPVC?

A: Both parts are parametric equivalents with identical electrical specifications (4.5V ~ 5.5V supply, 24mA output current, -40°C ~ 85°C operating range) and the same 48-BSSOP package. The primary difference is manufacturer (Renesas versus Cypress) and packaging format (tape and reel versus bulk). Selection depends on procurement requirements and supplier availability.

Q: Why would I choose 74FCT16244ATPVG over 74FCT162244ATPVG8?

A: 74FCT16244ATPVG provides higher output current capacity (32mA high, 64mA low) compared to 74FCT162244ATPVG8 (24mA both). Choose 74FCT16244ATPVG if your application requires higher drive capability or lower output impedance. Both maintain the same supply voltage and operating temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Not all substitute parts explicitly list ROHS3 compliance in the provided specifications. CY74FCT162244TPVC, 74FCT162244ATPVG8, 74FCT163244APVG8, 74FCT163244CPVG, 74FCT163244CPVG8, and 74ACT16244DL are confirmed ROHS3 compliant. Verify compliance status with the manufacturer for parts where this specification is not provided.

Q: Can I use 74FCT163244CPVG in a 5.5V system?

A: No. 74FCT163244CPVG operates at 2.7V ~ 3.6V supply voltage and is not rated for 5.5V operation. Using this part in a 5.5V system will cause device damage. This part is suitable only for low-voltage applications.

Q: What is the difference between tape and reel (TR) and bulk packaging?

A: Tape and reel packaging is used for automated assembly processes and provides parts in continuous strips. Bulk packaging is used for manual assembly or smaller quantity requirements. Both formats contain the same die and electrical specifications; the difference is in delivery and handling format.

Q: Is 74ACT16244DL still available for new designs?

A: 74ACT16244DL is classified as Last Time Buy, indicating limited remaining inventory and no future production. This part should not be selected for new designs. Use active alternatives such as CY74FCT162244TPVC or 74FCT162244ATPVG8 instead.

Q: What is the Moisture Sensitivity Level (MSL) and why does it matter?

A: MSL indicates how long a component can be stored in ambient conditions before requiring baking before reflow soldering. MSL 1 (Unlimited) means no time restriction. MSL 3 (168 Hours) means the part must be soldered within 168 hours of opening the moisture barrier bag. Check your manufacturing process requirements when selecting parts with different MSL ratings.
